September 22, 1607. Alessandro di Cristofano di Lorenzo del Bronzino Allori (31 May 1535 - 22 September 1607) was an Italian portrait painter of the late Mannerist Florentine school.
Portrait of Grand Duchess Bianca Capello de Medici, by Allori, Dallas Museum of Art.
"The Duchess is wearing natural pearls in her hair, on her forehead, ears, neck and sewn on her brocade silk coat.
Natural pearls are found randomly by diving in the open seas making them the most valuable and rare pearls. After finding the pearls, they then must be matched for size and color for assembling into jewelry." Janet Deleuse
